Update a pull request

PATCH/repos/{owner}/{name}/pulls/{number}

Only the fields given change. Its author, or whoever asked g1t for it, may change it; anyone else needs the Triage role or higher. A new base is a pull.base_changed event: it leaves the merge queue, and whether it is behind, merges cleanly and has the checks it needs is worked out against the new base. state open reopens a closed pull request, as reopen_pull_request does, before anything else changes; state closed closes it, as close_pull_request does, after.

A new base takes it out of the merge queue, and whether it is behind, merges cleanly and has the checks it needs is worked out against the new base.

• Authentication: Required. Send an access token as Authorization: Bearer.
• MCP tool: pull_request with action update, and the same inputs
• Scope: An access token needs pull_requests:write.
